original application filed July M, 1912, Serial No. 711.302. Divided and this application filed January 19,

' 1914. Serial No. 813,121.

To all whom it may concern lie it known that 1, Ernest .l-l'n 'oennm,

n. citizen of the lnitcd States, residing at (1 harks City, in the county of Floyd and finite of Iowa, have invented. a certain new and useful lm rorement in Eleetrkally Operated Type- 'riters, of which the fob lowing is a specification.

My invention relates to improvements in electrically operated typewriters of that class in which. by the depression of a key, :1 sell-write rlertromagnet is energized to there in; more o. type bar operating device to position to opemtively engage a universal ogwroting hzir, said universal operating bar lu ing or met.

This misc divided out my cmi ponion application filed by me on July is. 1912, Saris! Nnn'ihcr 3'1 1,6012.

The oldect of my invention is to provide impr ved electromagnetic means of si1nplc. durnllo and inexpensive construction ope! Jvely connecting: any one of the of type luir operating levers to a uni rszil operating bar.

Billion spcrilicully, it is my object to provide on improved construction in which the more mounted on and car'- type hm; operating le ers so that tiling the dmivc o hookwil mtch for el 'e rtromnpnot to operate said i. may both he permanently con- :rrr wmd ing type her operating 1 when the type lnir operating r ..cr J .trni. or mwongrnient oi the selectiveelertromngncls or the hooked catch is necessary.

M invention coi'zsists in certain details, in

mtruction. arrangement and comhination of the tnrions parts of the device.

' plated are at lull v set forth, illmtrotcd in m which:

s. and part of the unive sal in turn operated by an elertropower l n mirei. operating her and a by the type her operating levers, and. Fig. 3 shows at detail view illustrating one of the hooked catches and connected parts.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate generally the frame of the typewriter. On this frame is a. sliding carriage 11 of ordinary construction containing the platen 152. The carriage is provided with an ordinary spacing mechanism illustrated gener ally by the reference numeral 13, which spacing mechanism is automatically operated in a manner to be hereinafter more fully de scribed,

Mounted in the front of the typewriter frame is a series of keys 11, each of which rests upon :2. spring 15 which when depressed, engages an electrical conducting bar 16 and closes an electric circuit from said her through the depressed spring. Mounted upon the frame in semi-circular arrangement. below the platen. is a. series of type bars 17, pivotally supported on a curbed. shaft 18 and each provided with an upwardly projecting lug 19. Immediately in the rear of and below the shaft 18 is another shaft 20 extending across the machine, and pivoted to this shaft 20 a series of swinging levers 21. The levers -21, odout to the ends, have their upper portions inclined upwardly and inwardly in o dircction toward the printing center of the platen, and at the upper end of each of the levers 21 a link 22 to connect it with the corresponding lug 19. Arranged near the bottom of the typewriter frame, and extended transversely across the frame is a hearing shaft 23 to which is pivoted a series of oscillating levers 24:, one for each of the levers 21. At the upper end of eachof the lovers 21 1s a llnk 25 connecting 1t with the corresponding lever 21. The links 25 that connect the central levers 21 are attached to the levers 21. near their lower ends, while the links that are connected to the outer levers '21 are connected thereto near their upper ends. as shown in Fig. 1. The

arrangement is such that if any one of the.

and that may be made from the same set of dies.

For the sake of convenience in writing the claims, I shall call the bars 21 the first series of type bar operating levers and the levers 24 the second series of type bar operating levers.

Pivotally connected to the shaft 23 are the arms 37 which are fixed at their upper ends of the horizontal universal operating bar 38. The upper and lower edges of this bar are beveled or inclined at 39 to coact with the beveled end of the hooked catches 76 to be more fully described.

For moving the universal operating bar 38 rearwardly, I have provided an electro power magnet 61 secured to the back of the frame 10. Pivotally supported below the power magnet are the arms 59 which support the power armature 50 adjacent to the power magnet 61. The link 62 connects the power armature 50 with the universal op erating bar 38.

To cause the type bar operating lever 24 to be actuated when the universal operating bar 38 is moved rearwardly upon the depression of any one of the keys H, I have provided the following mechanism: Fixed to each alternate type bar operating lever 24 is a bracket 75 having an uynvardly extending and 75' and fixed to each of the type operatiiig bars, between these, I have provided a similar bracket having a downwardly projecting end 75". livoted to each of the levers 24 carrying an upwardly extending bracket 75, is a catch 76 having a downwardly extending hook. Each of the levers 24 carrying a bracket with a downwardly extending end 75 is provided with a similar catch 76 having an upwardly extending hook. Each of the catches 76 is provided with a downwardly extending armature 77, and each of the catches '76 is provided with an upwardly extending armature 77". Each of the upwardly extending brackets 75 is provided with an electromagnet 26 in line with the corresponding armature 77 of the catches 76. Each of the downwardly extending brackets 75 is provided with a similar electromagnet designed to operate the armature 77 of the catches .76. The catches 76 are designed to be moved to their lower limit of movement by means of springs 78 and the catches 76 are designed to be moved to the upper limit of their movement by means of springs 78. A stop 20 is provided on each of the levers 24,

to limit the movement of the catches against the action of their respective springs.

Each of the electromagnets 26 is connected to a corresponding key 14 through the wires 61 and with the battery by means of the transverse bar 68 and the wire 68' which form a part of the electric system shown in my companion application above referred to, the magnets 26 being energized in the same manner by the depression of any one of the keys 14. Thus, it will be seen that when any one of the keys 1% has been depressed, a corresponding electromagnet will be energized which will in turn cause the corresponding catch device to engage the universal operating bar 38, after which the electro power magnet 61 will operate the armature 50 and it in turn will operate the bag 38 through the link 62 and then the levers 24 will be moved rearwardly and the corresponding type bar 17 will be operated through the links 22 and 25 and the lever 21.

It is obvious that the design and arrangement of the selective magnets and selective hooks are extremely simple, the construction being compact and having few parts, and the operation of the parts being consequently attended with a minimum of friction, wear and lost motion. Further the parts may be readily and easily assembled or detached.
